How does one get into survey work??
Well first there is a complex operation involving the removal of half your brain....just kidding
A low level endorsement is what you need, absolute minimum 500hours is the lowest i've heard, preferably more; A desire to get out of the house...and not come back for months at a time; lots of books and DVDs to keep yourself amused in the far reaches of the outback, and then its merely a case of hunting down a job with one of the previously mentioned companies listed up the page.
Is there much work??
Not really, its not the best time to be getting into it. Its not ideal being in it right now although there are a few govt. contracts keeping bread on the table for now. Last on first off tho....and its going to be pretty patchy out there for awhile.
I'd be interested to know if anyone else is doing much mine work?
